Abstract: The medullary cavity barrier is made of a metal in a rosette manner with leaves which are permanently and elastically deformable. The barrier is porous to the extent of being permeable to blood, fat and gases but impermeable to the passage of bone cement. During implantation, each outwardly extending leaf bends relative to a central core to fix the barrier within a tubular bone.

Abstract: The method is intended for guniting of a metallurgical plant the walls (13) and the bottom (14) of which are lined with a refractory material. The method consists in directing one portion of oxygen, in the form of a jet, to the zone of the bottom (14) to obtain carbon monoxide, and another portion of oxygen, together with a refractory powder, to the lining to be restored, a powder-like fuel being continuously fed together with the jet of oxygen which is directed to the zone of the bottom (14). The method is implemented with the help of a multi-nozzle tuyere (1) comprising a cooled casing (2) with pipelines for supplying the refractory material, the fuel and the oxygen, said pipelines being mounted coaxially inside it, and also comprising nozzles (7, 9, 6 and 8) respectively for feeding the refractory material, the fuel and the oxygen, some (6 and 7) of the nozzles being mounted on the side wall of the tuyere (1) and serving to feed, respectively, the oxygen and the refractory material to the lining area to be restored, and the other (8 and 9) nozzles being mounted on the butt-end side of the tuyere (1) and serving to feed the oxygen and the fuel to the zone of the bottom (14) of the metallurgical plant. The total surface area of the cross-sections of the nozzles (6) for feeding the oxygen to the lining area to be restored essentially is equal to the total surface area of the cross-sections of the nozzles (8) for feeding the oxygen to the zone of the bottom (14) of the metallurgical plant.

Abstract: The printed circuit board is subjected to a microscopic examination to identify faults, such as circuit breaks, short circuits, etc.  The circuit board is viewed as a matrix field of cells that are defined in size to suit the required accuracy. Within each cell a specific amount of copper or total absence of copper is required. The plate is optically scanned by a line camera and the output is related to the reference values of the cells.  Any fault results in a change in the contrast value which is identified.

Abstract: A plurality of hoppers or bins which are product-loadable from above are uniformly spaced from each other and are transported along a path of conveyance. The hoppers or bins, each of which is bounded by two walls or faces which are substantially transverse to the direction of conveyance, pass by a plurality of individual infeed conveyors which are staggerdly arranged in the direction of conveyance. These individual infeed conveyors possess controllable grippers or clamps which are spaced from one another. These mutually spaced clamps or grippers are used to load or fill each hopper or bin with a printed product. The mutual spacing of successive clamps or grippers and their circulating speed substantially correspond to the mutual separation distance or spacing and the circulating speed of the hoppers or bins. In order to accommodate as many hoppers or bins as possible per unit length of the path of conveyance of the hoppers or bins and still assure the problem-free loading of the hoppers or bins, each individual infeed conveyor passes over the path of conveyance of the hoppers or bins with its product transfer or delivery region inclined or sloping towards the path of conveyance. Furthermore, the product transfer or delivery region of each individual infeed conveyor is provided with a guide plate in order to guide the freely suspended edges of the printed products into the loading or infeed opening of the hoppers or bins.

Abstract: The measured complex impedances and power values are pref. frequency matched, classified and filtered before being fed to analog-digital convertors. The digital values are divided into time segments with the same number of values and the segments are normalised to zero arithmetic mean and subjected to proportional scaling. The cross-correlation functions of the measured voltage and current are formed and the max. values of the functions and their timing are used to classify the condition of the system. The product and quotient of the Fourier transforms of the voltage and current are formed for associated frequency ranges to produce a power and impedance spectrum for system assessment.

Abstract: An x-ray lithography system is disclosed in which x-rays (56) are generated by directing a high energy laser beam against a metal target (26) to form an x-ray emitting plasma. The x-rays from the plasma are then directed through a mask towards a resist covered wafer (58) to cause a patterned exposure on the wafer resist coating. The mask, the portion of the target which the laser beam strikes and the portion of the wafer to be exposed are all within an evacuated chamber (22). The laser, prior to entering the chamber,is split into two separate beams (24, 24A), each of which are focused and directed through a window (70, 72) in the side of the chamber towards the same spot on the target. Apparatus, including an air bearing, seal and positioner, is provided to move the target at periodic intervals. Similar apparatus is provided to move the wafer from exposure section to exposure section. The laser beam system includes a face pumped laser beam amplifier (188) and unidirectional beam expanders (232, 280) to allow the maximum energy to be transferred to the laser beam by the amplifier. A series of two or more laser pulses are provided in order to maximize the energy obtained from the laser amplifier. A magnet (76) and a membrane (77) shield are also provided to prevent high energy particles and dust contaminants from the plasma from effecting the lithography process. A materials handling device (14) is provided for moving wafers, targets and masks and an alignment system operating within the evacuated chamber, positions of the wafer with respect to the mask prior to the exposure thereof.

Abstract: The spin axis of a geosynchronous satellite is oriented at a direction angle which equals the inclination angle of the current orbital plane plus an adjustment or correction angle (B), when the inclination angle is greater than zero. The correction angle is determined using one or both of the following equations: (1) and (2) where, BS = the elevation angle of the bore site target in spacecraft coordinates, bs = the latitude of the bore site target, I = the inclination angle of the orbital plane with respect to the equatorial plane, and B = the correction angle with respect to orbit-normal to point the axis of the beam at the desired bore site target. Orienting the satellite at the direction angle is performed by thrusters. A magnetic torquing system may also be used.

Abstract: Techniques for introducing information into a data stream first obtains the spectral values of the short-term spectrum of the audio signal. Separately, information to be introduced are combined with a spread sequence obtaining a spread information signal, whereupon a spectral representation of the spread information is generated, then weighted with an established psychoacoustic maskable noise energy to generate a weighted information signal, wherein energy of the introduced information is substantially equal to or below the psychoacoustic masking threshold. The weighted information signal and the spectral values of the short-term spectrum of the audio signal are then summed and afterwards processed again to obtain a processed data stream including audio information and information to be introduced. Because the information to be introduced are introduced without changing to the time domain, the block rastering underlying the short-term spectrum are not touched, thus introducing a watermark will not lead to tandem encoding effects.
